I had the same problem some time ago (I have IRC logs online, and too long words cause horizontal scrolling, which is evil, so I had to break up words), and I solved it roughly the same way as you did.

I can only add that it's a bad idea to use $&, because it will slow down regex matches in your whole script, and even in modules included from your script.

Use $var =~ s/(\S{$last_length})/$1\n/sg; instead.
